The urnp included in the machine for circulating material-treating liquor is preferabl of the centrifugal type, and it is providetf with. a larger feed- )ipe than outlet, to insure a regular flow 0 liquor by always having the pump full.

Generally, the invention provides an apparatus, for use in dyeing or otherwise treating with liquor wool, cotton, or other permeable materials, which shall be simple in construction, strong, durable, and efficient in operation, and capable of being placed directly upon any suitable floor without the necessity of cuttin away the floor or the provision of a speolal or expensive foundation.

when read in connection with the description herein, the details of construction and arrangement of parts contemplated by the invention will be apparent from the accompanying drawin formin part hereof, wherein an emb iment of t e invention, as applied to a dyein and bleaching machine in which'the material-treating liquor enters the material through a foraminous member at the bottom and leaves it through a 'foraminous cover, is disclosed, for purposes of illustration.

be -variously organized, without departing in the least from the nature and spirit of,

the invention, and that it is not'the inten tion to be necessarily limited to the precise delineation of the invention herein in' interpretation of claims hereinafter.

Like reference-characters refer to corresponding parts in the several views of the drawings, of which .4

Figure 1 is a side view, partly in section, of a dyeing andbleaching machine in which this invention'is embodied; Fig. 2 is a plan view, the circulating system being omitted; Fig. 3 is a sectional view of the false bottom and its distributing'member; and Fig. 4 is a plan view of the false bottom.

The machinejincludes 'a vat or tank 5 for containingthe material to be dyed, bleached, or otherwise treated. Sides 6 of the tank are preferably vertical. A bottom 7 is adapted to rest directly" upon the floor of a dye-house or other place. 'A seat 8- extends around the sides inside of the vat near the bottom, and is adapted to'support a false bottom or lower fora'minous member 9 'a suitable distance from the vat-bottom 7. The member 9 is preferably a flat plate having a central opening 10 and smaller perfoan increasing amount of space in the vat from the fal'sebottom upwardly. While it is preferred to have the member 12 circular in cross-section, it will be understood that it may be made in other sectional shape, such as polygonal, so long as its lateral sur face approaches the sides of the vat from the foraminous member through which the liquor enters toward the member throughwhich it is discharged and that it occupies more of.the vat toward the discharging member tl1an-in the vicinity of the receiving-member, th ereby making the materialholding capacity of the vat less-toward and at the discharging-member than at'the receiving-member. The casing 12 is formed with perforations 15 through its lateral face for about twothirds the-distance from the false bottom, and the top and the remainder an air-chamber casing.

of the lateral face are im erfor-ate, whereby is forme in the top of the ,loo

In using the machine, the material to be treated is packed in the-vat on top of the false bottom and around its central extending portion, and then an upper foraminous member or cover 16 islet down over the packed material. The cover isformed with perforations 1.7, preferably of less aggregate capacity than those of the false bottom and its extending member, whereby pressure of liquor may be maintained between the falsebottom and cover. The cover is held down in place .on the material by. jackscrews 18 in engagement therewith andwith removable lugs 19 projecting fromthe 'vatsides. The vat is provided with aliquorentrance 20, leading into the space beneath the false bottom. and with a liquor-exit 21, positioned just above, the cover 16 when the cover is in its normal position in'the vat,

a-'nd below the normal surfacc-level of the liquor in the vat. "lhe exit leads to a steambox 22 at the side of the vat. Steam-pipes 23 and. 24, to maintain the material-treating liquor at the proper temperature, ,ai'c POSI- tioned, respectively, in the space in'the' vat below the false bottom and in the steambox; and they are supplied with steam from a boiler or other suitable source, not shown.

Dyeing, bleaching, or other materialtrcating liquor is furnished to and circulater] through the vat by means of a system which int-bales a pipe 25, leadine to and eonneeted with the vat at the entrai'ice 20. A fetal-pipe 2b. leading from any suitable source of supply, sueh as a. (lye-storage tank (not shown), is connected to pipe l) \j' a T 27, in which there is a three-w ly valve. A pipe 28 leads from the lower portion of the stean'i-box to the slietioirenlranee of a pump 25) and in this pipe, betaveen the steai'n-box and pump, there is a T 30, to which is connected a pipe 31, leading to a. T 3-2 in pipe "JSbetween the liqnor-entrance 20 and the teed-pipe 2(3. The T3; 30 and 32 each contains a three-way valve. A pipe 33, leading from the discharge portion of the pumpJis connected topipe 25 between the feed-pipe Qti and the T 32. V

The pipe Q8, leading from the steam-box to the pump, is of greater capacity than the pipe 25, lea ding to the bottom of the vat, in orderthat the pump may at all times receive an adequate flow of liquor to keep it full and a taster discharge than inflow pre 'entecl. This insures reliable operation in case a centrifugal pump, which is preferred, need. A valve-control]ed pipe 34 leads .tom the hottom'of the steam-box to a sewer or other deeired place. of disposal, in order that the box maybe drained when desired. The portion of pipe extending beyond the T 27 also leads to a sewer or other disposal, place. A valve-controlled water-suppl pipe 35 leads 'into pipe Ella tween the T e 30 and 32.

The .nlai-hine may be operated as follows:

The valves are set. to lead liquor from the pipe Elli through pipe 25 into the vat, and the liquotgis permitted to so tlow'until it has passed through the false bottom and its externling iuciriber', through the material packed. thereon and therearound, and through the rotor, and attained a level aljio've the exit 21, through whieh it flows into the SlCtHlF-l'NJX. Then the valves are to. close the pipe 25 at T 2?, to open pipeBS from the steam-box to the. puuip, and to close pipe I'll. 'llmreupon, the pump is started: and operated and liquor circulated frointhe eteanebox through pipe 28, the pump, pipe 33, and pipe to the bottom of 'the'ratt, and theuee'foreed u nvardly'tluaiugrh the false bottom and radially or outwardly from the central n'iernber into and through the-material under treatn'ient, anu through the cover, from above which it flows through exit -21 to the steanrbox. The alve in titer-simply pipe l5 elosed during this operation.

The liquor, in being forced upwardly and radiallythrough the material from the false bottom and its central. u wardlv-extendiin portion or mei'nber, will tend to move the material upwardly toward the cover into the smaller snaee tor-merit by the central liquor evenly forced through the materialand the material uniformly treated.

The upper portion of the central member 1.1 of: the false bottom, which isdetined by the imperforate portion thereof, forms an expansion=ehaniber, wherein air will be compressed by'the pressure of the liquor rising above the perforations 15. If any diminution in the pressure of the liquor occurs, the air coiiipressed in the ehamber will torch tl'ie',liqi.ior below it iloirnasardly and outwardly and thus contribute to the maintenance of aregular flow of liquor through the material under treatment.

The liquor-exit. 21, being positioned below the normal surface level of the liquor in the vat, foa1n,-'.,scum, and the-like floating on top of the liquor will not flow to the steambox and will, therefore, not be circulated through the mass of material under treatment. The introduetion of scum and the like which forms on the top of Clyediqnor often results in the appearance of Streaky blotchee in dyed imiterial, particularly in thatpart: into which the liquor first. tlows.

'ben it is desired to drain the vat of liquor,- the valve in T 27 is set so as to direct [low either into the feed-pipe 2(3 or so theportion of pipe 25 leading to a sewer,

dependent upon whether it i:-:drsired to return the liquor to the storage-tank or release it from further use, The valve in T 32 is set to direetllow upwardly into pipe 31 and to prevent. llow toward T .57, and t-hevz-ilvein T 30is act. to direct. [low 7 pipe 28 and thence to the pump and to shut, ott' flow to or from the steam-box through pipe. 28. \Vith the valves; so set, the pump will operate to draw the liquor from the bottom of the vat and foree it to the storage.- t'ank or to the sewer, as desired.

lVater may be introduced into the vat "for washing or other purposes by 'setting the valve in T 32 so that liquid may flow along pipe 'nto the val at entrance 20, but not upwardly from that pipe into pipe 31, the valve in T 27 being-closed against, all passage; by setting the valve in T l-l0 to direct flow from pipe 31 tlil'olijh pipe 28 to the pump and to prevent flow between that pipe and the steam-box; by opening the valve-in pipe 35; and by operating the pump to force the. liquid through pipe 33 into pipe 25. When. a sufii'eient; quantity ofwater has been introduced into the vat and itis defrom pipe 31 into.
